WebbThe heart—based on the resting heart rate—is under parasympathetic tone, and the blood vessels—based on the lack of parasympathetic input—are under sympathetic tone. The vagus nerve contributes to the lowered resting heart rate, whereas the vasomotor nerves maintain the slight constriction of systemic blood vessels. WebbSome degree of resting tone is normally present and therefore permits a small degree of bronchodilation when vagal tone is reduced in a similar fashion to vagal control of heart rate. 2.
